While millions of people rejoiced at the news of this year’s Roseanne revival, many others expressed their concerns of Roseanne Barr’s controversial views. As an unapologetic Trump supporter, Roseanne’s opinions were somewhat unique compared to the majority of Hollywood, but even many of those who disagreed with her politics agreed to work with her or were at least excited to watch the show.

But after a troubling Twitter tirade on May 29 — her worst to date — ABC abruptly canceled Roseanne, and even her staunch supporters began to question her mental health. Roseanne has always seemed a little volatile on social media, but her latest rant went way too far.

First, she went after Chelsea Clinton

On the morning of May 29, Chelsea Clinton politely responded to a tweet from Roseanne calling her “Chelsea Soros Clinton.” Clinton explained that her middle name was actually Victoria and she wasn’t married to a Soros, as Roseanne had implied. Roseanne apologized, but added that Clinton was actually married to “the son of a corrupt senator,” and promptly retweeted some scathing insults directed toward Clinton from some of Roseanne’s fans.

Then, in a response to another Twitter tirade (which has since been deleted), Roseanne went after Valerie Jarrett, a former senior advisor to President Obama. She wrote “muslim brotherhood & planet of the apes had a baby = vj.” The tweet was spotted by thousands of Twitter users, who instantly pointed out its racism and called for Roseanne to be penalized.

Next: Roseanne clearly realized her mistake.

Roseanne apologized right away …

“I apologize to Valerie Jarrett and to all Americans,” she tweeted. “I am truly sorry for making a bad joke about her politics and her looks. I should have known better. Forgive me — my joke was in bad taste.”

Roseanne promptly announced “I apologize. I am now leaving Twitter,” something she had threatened to do several times before.

Within minutes, ABC had issued a statement, announcing that they were cancelingRoseanne immediately.

“Roseanne’s Twitter statement is abhorrent, repugnant and inconsistent with our values, and we have decided to cancel her show,” ABC Entertainment president Channing Dungey said. The announcement came just after Wanda Sykes, who worked as a producer on the show, said she wouldn’t be returning to Roseanne.

Series showrunner Bruce Helford issued a separate statement, saying: “On behalf of all the writers and producers, we worked incredibly hard to create an amazing show. I was personally horrified and saddened by the comments and in no way do they reflect the values of the people who worked so hard to make this the iconic show that it is.”

Next: Celebrities instantly began to show their support.

Celebrities’ reactions were supportive

Immediately, celebrities began to respond to the news that Roseanne had been canceled. Debra Messing, Minnie Driver, Viola David, and Alyssa Milano all praised the decision, while Roseanne’s ex-husband Tom Arnold composed a few snarky tweets in support of the cancelation, adding “but maybe someone else find out if I’m still banned from all of @ABCNetwork for calling Roseanne Barr out first on her racist conspiracy tweets.”

“Roseanne’s recent comments about Valerie Jarrett, and so much more, are abhorrent and do not reflect the beliefs of our cast and crew or anyone associated with our show. I am disappointed in her actions to say the least. This is incredibly sad and difficult for all of us, as we’ve created a show that we believe in, are proud of, and that audiences love — one that is separate and apart from the opinions and words of one cast member.”

Next: Is this Roseanne being extreme, or Roseanne being Roseanne?

This Twitter meltdown seemed a bit extreme, even for Roseanne, who has a history of controversial tweets. After all, the actress does have a history of mental illness, and she’s had several nervous breakdowns in the past. Many of her fans began to wonder if the public should be showing concern rather than outrage.

But all it takes is one scroll through her Twitter feed to see that this is most likely par for the course. She recently accused young activist David Hogg of giving a Nazi salute at a rally, and in the not do distant past, she’s embraced numerous conspiracy theories. And many of her former fans were never able to forgive her for the shocking 2009 photo shoot in which she dressed as Hitler while pulling people-shaped cookies out of an oven.

Racism is not a mental illness

Roseanne may still be struggling with mental health issues, but racism alone is not a mental health disorder. And since there’s no doubt that her Valerie Jarrett insult was racist, she’ll have to do some serious damage control if she ever want to return to the public eye. It remains to be seen what Roseanne’s next move is, but the popular opinion seems to be that ABC execs made the right call in canceling the show.
